Diagnosis.

The genus closely resembles Siler Simon, 1889 , but can be distinguished by: (1) the larger body size (6 – 10 mm); (2) the male femur I with only sparse setae (Figs 4 B, E, F View Figure 4 , 5 O View Figure 5 ; femur I and tibia I covered with dense setae in Siler ); (3) the male palp with a blunt posterior tegular lobe ( PL) (Figs 8 B, C View Figure 8 , 10 A View Figure 10 , 11 E View Figure 11 , 12 D View Figure 12 ; PL longer and narrower in Siler ); (4) the chelicerae with dense brown setae on the front surface (Figs 1 B, D View Figure 1 , 5 M, N, P, Q, T, U View Figure 5 , 6 E, F View Figure 6 , 7 A, C, E View Figure 7 ; setae sparse in Siler ); (5) the presence of accessory glands (AGs) (Figs 9 B – F View Figure 9 , 10 D View Figure 10 , 11 B, D View Figure 11 ; AG not observed in Siler ).

Description.

Medium-sized spiders (total length 6.51–8.00 in males, 7.98–10.00 in females). Body dark with pale yellow patches, covered with dense scales (Figs 3 A, B View Figure 3 , 4 A – L View Figure 4 , 5 A – D View Figure 5 , 6 A – D View Figure 6 , 7 B, D, F View Figure 7 ). Chelicerae with brown setae on front surface (male also with sparse blue scales), with two promarginal teeth and one retromarginal tooth (Figs 1 C, D View Figure 1 , 3 C View Figure 3 , 4 B, E, F, H View Figure 4 , 5 P – U View Figure 5 ). Femur I of male covered with short and sparse setae (Figs 4 B, E, F View Figure 4 , 5 O View Figure 5 ). Male palp (Figs 8 A – F View Figure 8 , 10 A, B View Figure 10 , 11 E View Figure 11 , 12 C – E View Figure 12 ) with short embolus, palpal bulb with tegular bump at lower right corner. Female epigyne large, copulatory ducts short (Figs 9 A – G View Figure 9 , 10 C, D View Figure 10 , 11 A – D View Figure 11 , 12 A, B View Figure 12 ).
